GMC generators

Also check resistance readings on Red & black wire 32 ohm. Brown & black 668 ohm. The red & black wires are triger coil. TheBrown & black are the HV coil . This system used is a CDI ignition. Daryl

jaycar don't seem to have that kit listed anymore.
is this the one?

correction jaycar do have it, part number is kc5466 ;)

OOPS Typo thanks greybeard. Daryl

Hi outsider, First try fitting a new spark plug, found if you dont run them with a reasonable load the plug seems to give trouble. Local plug types areW8DC Bosch or BP6ES NGK.

I have tried a new plug no difference, Just had another go at starting it. It will fire almost every time, runs for a second or two and sound like it is going to keep going then just stops ?

Bit hard to say outsider, normaly a carby bowl full of fuel will run them for quite awhile, perhaps the CDI module is breaking down????? I keep acouple of the Jaycar CDI kits handy for cheking generators & outboards when a CDI unit is suspect. Its certainly cheeper than using the Manufacturers units & the components used are fairly robust. Daryl

I had same problem. Stale fuel !!! Tip out old stuff , empty bowl and refill with fresh fuel. Goes well now. Only engine that I have had this problem with !!

Outsider,drain carby and remove and clean/ream the main jet with fuse wire,mine was the same ,it would hunt but not run cleanly, the job is easy and should fix the problem for you,small engines need clean fuel.

With 2stroke fuel, the petrol evaporates over time, leaving a mix that is too oil rich. The oil rich fuel will not flow properly in the carby because it is too thick. That is why it will start but not keep running.

G'day dbish, what is a CDI unit/module.

G'day outsider, there may be an easy start decompression device staying open once the engine has started. Happy Days.

Hi Farmboywa, There is no easy start decompression on these generators. The CDI unit is what fires the ign coil on nearly every outboard motor, generator & motor bike. There is a highvoltage winding for the unit powered from the flywheel & there is a triger coil which tels it when to fire the ign coil, that is a very basic description, It is usualy just a black box with 4or5 wires coming out of it. un fortunately i cant post pictures here. Daryl

Wizard not every one can afford Honda & ive never had any trouble with my GMC. My other Geny is a 2600W Kipor also trouble free & eats a Honda when it comes to Aircond. Cheers Daryl

Trust me dbish you'll find the money so you are stuck again.

When your camping a few hundred K's from Darwin in Arnhem land and you have this GMC boat anchor that won't start after running for only a few hours but all you can hear from a nearby campsite is the hum if a Honda...you wish you had that nice red quite unit that guy has.

It is worth every cent I payed for it!

Greyhound busfreight out of Townsville is reasonable you can book and pay on your end then the seller only has to drop it off at the depot

hi henry45, Where are you located? I have a GMC generator that is a bit dirty but in good working order which is surplus to our needs. It is located in Lysterfield Vic. We are relocating the famiily to Adelaide on 19 March and if you want it you can have it for free to use or break down for parts. Only thing though is you would need to pick it up as I am already in Adelaide working and the missus will not be able to pick it up lol!

If henry45 doesn't want it then anyone else want it? trying to clear out some stuff before the move.

Hi Henry
What end of the country are you located

Cheers

Hi Henry,
I have a 650w GMC you can have cheap. It was running well but I broke the fuel tap and haven't replaced it yet so has been out of action for twelve months. I live in Bundaberg but am away at the moment and won't be back for about a week. Let me know if you are interested and I will arrange to let you have a look when I get back.

Cheers

Thanks kevh & wysiwyg--could not see bundy listed on site -am getting part from sydney-yes-wysiwyg-catch up when you return-can we send addresses phone etc on this-?may be an opening for a business dealing with GMC???!!!Not me though!--kev-
